CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 245,561, dated August 9, 1881.

Application filed June 17, 1881. (No model.)

To all whom it may concern:

Be itknown that I, J EssE .H. QUACKENBUSH, a citizen of the United States, residing at East Saginaw, Saginaw county, Michigan, have invented an Improvement in Gar-Couplings, of which the following is a specification.

My invention relates to certain improvements in the car-coupling for which Letters Patent of the United States No. 235,648 were granted to me December 21, 1880, the main objects of my present improvements being to render the coupling stronger and more compact than before. These objects I attain in the manner which I will now proceed to describe, reference being had to the accompanying drawings, in which- Figure]. is a sectional view of one draw-head of the patented coupling; Fig. 2, a vertical section of the improved coupling, showing the coupling-link locked to one head and the pin of the other head set for engaging the link; Fig. 3, a sectional plan view of part of Fig. 2, and Figs. 4 and 5 detached perspective views of parts of the coupling.

The patented coupling had a slotted drawhead, A, adapted for the reception of a vertically-sliding block, B, and furnished at the top with lugs, to which was hung a lever, D, the latter being suitably weighted and having a projectioma, which served as a support forthe coupling-pin E when the latter was elevated, the lower end of the lever being struck by the coupling'link as the latter entered the drawhead, so that the projection to was withdrawn from beneath the pin E and said pin allowed to fall to complete the coupling, the link being maintained in a horizontal position after coupling by the weight of the sliding block B on the inner end of the link. The pin E was guided in an opening in the draw-head, and the amount of metal surrounding said opening at the rear of the pin was necessarily limited, so that the support of the pin when the latter occupied the elevated position shown was open to some objection on the score of weakness.

In my present coupler I discard this mode of guiding the pin, and adapt the latter to segmental recesses b d, formed, respectively, in the draw-head and in the face of the block B, as shown in Figs. 2, 3, and 4, so that blows 0n the pin E are resisted by the block, the breakage of which from this cause is practically impossible; and even if the block is injured, it can readily be replaced without the necessity of changing the entire draw-head.

In the improved coupling I have dispensed with the pivoted lever having a projecting finger for supporting the pin, and use in place of the same a trigger, m, which is adapted to a central slot, f, in the block B, and is pivoted to the latter, at the lower end, by a pin, t. When the coupling-pin E is elevated the front end of the trigger projects beyond the face of the block B, and serves as a support for the pin, the trigger being retained in this position by the contact of a projection, n, thereon with a shoulder, to, on the block B. The entering link strikes the projecting end of the trigger and forces the same rearward, so as to release the pin E and permit it to drop to complete coupling, as in other couplers of this class, the link, on further entering the draw-head, serving to elevate the block B, which rests on the inner end of the link and maintains the same in a horizontal position.

Besides the additional strength and security attained by the present method of guiding the pin, the trigger m is more compact and less liable to injury than the lever of the former coupling, the block B, with its trigger, forming a self-containedstructure adapted to be readily introduced into or removed from the recessed draw-head. The parts, moreover, are always in operative condition, as the shoulder w of the block and the projection n of .the

trigger insure the maintenance of thelatterin proper relation to the block, and the recessed face of the block serves to so guide the pin E that the proper support of the latter by the trigger is insured.

I claim as my invention- 1. The combination of the block B, having a slot, f, and internal shoulder, to, with the pivoted trigger m, occupying a position in the slotf, but adapted to project from the front of the same, and having a projecting finger, 01, adapted to bear on the shoulder to of the block, as set forth.

2. The combination of the draw-head, having a recess, 11, the block B, having a recess, to this specification in the presence of two subd, slot f, and shoulder 10, the pin E, guided by scribing witnesses. said recesses b and d, and the pivoted trigger m, adapted to the slot f, and having a projec- JESSE QUAOKENBUSH' 5 tion, n, for bearing on the shoulder to, as set Witnesses:

In testimony whereofI have signed my name EDWARD A. MOYE.
